The disclosure provides a method to detect sessile serrated adenomas/polyps (SSA/Ps) and to differentiate SSA/Ps from hyperplastic polyps (HPs). The method uses a molecular signature that is platform-independent and could be used with multiple platforms such as microarray, RNA-seq or real-time quantitative platforms.

The present invention relates to a novel monoclonal antibody which is specifically bound to a transmembrane 4 L six family member 5 (TM4SF5) protein. More particularly, the present invention relates to a monoclonal antibody which is specifically bound to a human TM4SF5 protein, to polynucleotides coding for the monoclonal antibody, to an expression vector comprising the nucleotides, to a transformant with the vector introduced thereto, to a method for preparing the monoclonal antibody, to a composition comprising the monoclonal antibody, to a method for treating liver fibrosis using the monoclonal antibody, to a method for treating cancer using the monoclonal antibody, to a method for inhibiting metastasis of cancer, to a method for diagnosing cancer using the monoclonal antibody and to a cancer diagnosis kit comprising the monoclonal antibody.

Provided is a peptide for targeting gastric cancer, a composition for diagnosing radioresponsiveness-dependent gastric cancer using the peptide, and a drug delivery use of the peptide, wherein a functional peptide capable of targeting cancer has been discovered so as to implement personalized diagnosis and treatment for individual patients having cancer, consideration of problems occurring during treatment in which treatment cases of respective patients differ due to different therapeutic responses resulting from genetic differences in the individual patients.

The present invention provides a method for diagnosing and determining prognosis of gastric cancer in a subject by detecting suppressed expression of the SCNN1B gene, which in some cases is due to elevated methylation level in the genomic sequence of this gene. A kit and device useful for such a method are also provided. In addition, the present invention provides a method for treating gastric cancer by increasing SCNN1B gene expression or activity.

Provided herein, in some embodiments, are methods for detecting a level of asparaginase (ASNS) in a sample obtained from a subject having or at risk for stomach cancer or liver cancer, and methods of treating the subject.

Described herein are high affinity antigen binding constructs, e.g., antibodies, directed to the ECD2 domain of HER2. The antigen-binding constructs comprise at least one antigen-binding polypeptide construct that binds to ECD2 of HER2 (HER2 ECD2) with increased affinity compared to a wild-type 2C4 antibody. Such antigen-binding polypeptide constructs comprise one or more amino acid modifications in the framework region and/or CDRs compared to the amino acid sequence of a wild-type 2C4 antibody that increase affinity of the antigen-binding polypeptide construct for ECD2 by 2-fold or greater. The antigen-binding constructs can inhibit the growth of HER2-expressing breast cancer cells and gastric cancer cells. Antigen-binding constructs in biparatopic format are internalized in HER2-expressing cells.

The present invention provides a method for evaluating the risk of occurrence of cancer in an individual.

The present invention provides a therapeutic agent for gastrointestinal cancer, comprising an Arid5A inhibitor as an active ingredient; and a method for screening for a candidate substance useful for treating gastrointestinal cancer, comprising the steps of: (1) examining whether a test substance affects Arid5A expression, and (2) identifying the test substance as screen positive when the test substance is capable of reducing Arid5A expression based on comparison of cases with and without the test substance.

The present invention generally provides a therapy for effectively treating and/or preventing diseases associated with cells expressing CLDN18.2, in particular cancer diseases such as gastroesophageal cancer. Data are presented demonstrating that administration of an anti-CLDN18.2 antibody to human patients with gastroesophageal cancer is safe and well-tolerated up to a dose of at least 1000 mg/m.sup.2. Furthermore, data are presented demonstrating that the antibody is fully functional in these patients to execute anti-tumor cell effects and evidence for antitumoral activity was obtained.

A method of processing a fecal sample from a human subject comprising combining a first portion of a collected fecal sample with a stabilizing buffer that maintains DNA integrity in a fecal sample, and combining a second portion of the sample with a solution that prevents denaturation or degradation of blood proteins found in a fecal sample. Embodiments comprise testing DNA extracted from the first portion of the fecal sample for the presence of a human DNA, and testing the second portion of the fecal sample for the presence of human blood.
